Problems solved by technology

Second, the chemical components such as the oil content of the treatment object are very unstable, and it is a great challenge to adjust the corresponding adjustment of the composition of the agent and the treatment temperature.
The third is that the oil content of sandy soil after treatment is difficult to reach the standard (national standard ≤0.3%)
[0003] At present, the methods for deoiling harmless oily sands are mainly thermal cracking and microbial methods, but the reaction conditions of thermal cracking are high temperature and high pressure, which has the disadvantages of being flammable and explosive, while microbial methods are affected by the natural environment, temperature, etc. , the impact of humidity is greater, and the processing efficiency is low

Embodiment 1

[0066] Such as Figure 1-13As shown, the harmless oil-sludge deoiling system of this embodiment includes a compound feeder 20, a ball mill 35, a swirl heating multi-module unit unit 34, a roller-sand disintegration kettle 60, and a separated oil storage device 36. Horizontal centrifuge 37 and pool 61; the outlet a19 of the compound feeder 20 is connected to the inlet of the ball mill 35 through a pipeline, and the outlet of the ball mill 35 is connected to the swirl heating multi-module unit The feed port b29 of 34 is connected by a pipeline, the discharge port b27 of the swirl heating multi-module unit unit 34 is connected with the feed port c42 of the roller sand-dispelling disintegration kettle 60 by a pipeline, and the shaft drive sand The separated oil outlet 44 of the disintegrating kettle 60 is connected to the separated oil storage device 36 through a pipeline, and the discharge port c45 of the shaft-driven sand disintegrating kettle 60 is connected to the inlet of the...

Embodiment 2

[0074] The present embodiment is the method for deoiling the oily sludge of the harmless oily sludge deoiling system of Example 1, the method is:

[0075] S1. Add drug a to the oily sand after preliminary sorting, stir until it becomes a paste, and obtain the material to be treated, which falls on the conveyor belt 2 through the feed hopper a1 of the compound feeder 20 The lower end is transported to the higher end and falls into the transfer hopper 8, and the material to be processed dropped by the transfer hopper 8 enters the main body of the conveyor 10 through the collecting hopper 9, and is pushed by the shaftless helical blade 17 through the discharge hopper. Port a19 enters the ball mill 35 through the entrance of the ball mill 35, and ball mills for 10 min at a temperature of 20° C. to 30° C. to obtain a pasty raw material; sodium) and water are mixed; the addition of the medicament a is to add 10 parts of alkaline detergent and 15000 parts of water in the oil and sand...

Embodiment 3

[0082] The system of the deoiling of the harmless oily mud sand of the present embodiment is the same as that of Example 1, and the method of the deoiling of the harmless oily mud sand of the present embodiment is:

[0083] S1. Add drug a to the oily sand after preliminary sorting, stir until it becomes a paste, and obtain the material to be treated, which falls on the conveyor belt 2 through the feed hopper a1 of the compound feeder 20 The lower end is transported to the higher end and falls into the transfer hopper 8, and the material to be processed dropped by the transfer hopper 8 enters the main body of the conveyor 10 through the collecting hopper 9, and is pushed by the shaftless helical blade 17 through the discharge hopper. Port a19 enters the ball mill 35 through the entrance of the ball mill 35, and ball mills for 20 min at a temperature of 20° C. to 30° C. to obtain a pasty raw material; Sodium) and water are mixed; The addition of described medicament a is to add ...

Abstract

The invention provides a system for deoiling harmless oil and sand, including a compound feeder, a ball mill, a swirling heating multi-module unit, a roller sand driving disintegration kettle, a separated oil storage device, and a horizontal centrifuge And the pool, also provides a deoiling method: add agent a to the oily sand, enter the ball mill through the compound feeder for ball milling, get pasty raw materials, send to the swirl heating multi-module unit, add agent b, separate The oil liquid enters the separation oil storage device, the primary separation material enters the roller sand flooding disintegration tank, and the agent c is added to react and separate. A decanter centrifuge centrifuges out the mud and sand, and the water enters the sump. The invention does not require special protective measures, does not produce substandard discharge, avoids high temperature and high pressure reaction conditions in the pyrolysis method and overcomes the influence of the environment on microbial degradation in the microbial method, and the oil content of the treated sediment is ≤0.3 %.

Description

technical field [0001] The invention belongs to the technical field of oil sludge deoiling, in particular to a harmless oil sludge deoiling system and a method for oil sludge deoiling. Background technique [0002] All major oil and gas fields in China have unavoidable emissions and leakages during oil production and exploitation. Long-term accumulation has caused serious soil pollution and hidden dangers of water pollution. At present, major oil fields have comprehensively carried out the treatment and treatment of contaminated soil in oil and gas areas in accordance with the specific requirements of the national environmental protection strategy. Among them, the deoiling and harmless treatment of oily sediment is the biggest problem. The difficulties mainly focus on the following three aspects: First, the composition of processing objects is complex and changeable. Oilfield oil sediment is generated and deposited in a wide range of areas, and the generation time can even...
